Realistically you only need an ebay blowoff valve, ebay piping kits are ok with good clamps, ebay intercooler, you should get a good name wastegate because thats what will blow your motor if it goes bad, a cast iron manifold, used turbo from a junkyard, and a few other random parts. If I had an older taco and didnt care I would do it. But a really good setup should cost 2000-3000 all said and done
